I've seen this sort of thing before, but not in a long time.I took it into Patterson Hyundai again after they said they would look at it.
..........It turned out to be a balancing issue. These are the "extra" weights they removed from my front wheels. They said they had never seen anything like this before and gave me the weight to take back to the other dealer and tell them how stupid they are.
It just proves once again that no matter how good the machines are, the mechanics will find a way to screw things up. This is why I always check lug nut torque anytime I think a mechanic has even been near the wheels.
